TAUNTON — Police say four more people have been treated for heroin-related overdoses in Taunton, three of them on Wednesday and one Thursday morning.

The latest overdoses bring the number of reported heroin overdose cases in Taunton this year to 85, according to Jennifer Bastille, the city’s Safe Neighborhood Program adviser.

The latest tally, Bastille said, increased by about 10 after a re-evaluation of previous incidents and reports indicated more heroin-related overdoses than previously thought to have occurred.

Police and other emergency responders, including firefighters and paramedics with ambulance company American Medical Response, have had to contend with a marked spike in the number of people overdosing on cheap heroin cut with the painkiller fentanyl.

Taunton police said seven people have died of heroin overdoses since the beginning of January.

The first report of an overdose on Wednesday was just before noon, when police responded to Prestige Car Wash at 13 Cape Road. An employee of the Route 44 business told cops she dialed 911 after finding a man in a bathroom who appeared to have overdosed.

They also said the man, who was transported to Morton Hospital for evaluation, later claimed to have overdosed in the bathroom after buying heroin from a person he’d met in the parking lot.

Police said he also claimed to have snorted the drug instead of injecting it.

Ronen Drory, owner of the Route 44 car wash/gas station/convenience store, said his manager on duty later told him she was “very suspicious” of the overdose victim and a woman after seeing them walk into the store together.

“He stayed and went into the bathroom, and she left,” Drory said.

He said his employee, after noticing the door to the men’s room was ajar, looked in and saw the victim turning blue and having some sort of seizure.

Drory said his employee, after calling 911, managed to jot down the license plate of the car in which the woman fled. He also said he provided police with surveillance evidence of the incident.

Drory said he considers the incident an anomaly: “This usually happens in the city, not on the highway.”

He also said he’s considering a bathroom policy whereby customers ask an employee for a key.

“It’s too bad that one guy can ruin it for everyone, because we have a good customer base. We get a lot of mothers with kids,” Drory said. “But we don’t want someone to die in our bathroom.”

The second overdose incident was just before 1 p.m. on Wednesday, when police say they responded to 53 Devon St. where a 20-year-old woman had been revived with Narcan.

The woman’s older cousin told police she called 911 and ran to a neighbor for help, and that the 54-year-old man performed CPR before paramedics arrived with Narcan.

Police said they subsequently received information that the heroin had been purchased in Brockton.

The third incident was at 4:30 p.m. on Wednesday, when police responded to 89 Seaver St. where a 24-year-old man was being treated with Narcan. The man, police said, was walking around and refused to be evaluated by AMR personnel.

The victim’s girlfriend allegedly told police she found him unconscious in the bathroom with his lips turning blue.

Police said they recovered two hypodermic needles and a dirty spoon from the residence.

The fourth overdose incident, police said, occurred shortly before 7 a.m. Thursday with a report of a man punching a light pole on the grounds of Parker Middle School on Williams Street.

Police said he was transported to Morton Hospital for evaluation.

Taunton Police Detective Matthew Skwarto said he’s not surprised that two of the more recent incidents involved people snorting, as opposed to injecting, heroin. He said most heroin users in the city don’t use needles.

Skwarto also said he’s not surprised that one of the overdose victims claimed to have bought the drug in Brockton.
